Don't be surprised to see students in other majors having more free time than you, as being in school for occupational therapy means more and tougher school work, and also means giving up much of your former life for two or three years. Be prepared for a lot of work and know that you may not make all A's, but in the end, know that occupational therapists are in demand and better paid than many other careers out there.
It's good to be aware of the many fields of occupational therapy in order to make an informed decision as to the direction you'd like to take. Occupational therapists can have different options for placements, therefore it is important to explore early on to get the most out of your education. There are also many different specialties that can be looked at, such as hand therapy or equine-assisted therapy (which is a collaborative effort between the therapist and a horse professional working with the client and horse to address treatment goals).
Keep in mind that schools have difficult admissions processes and very high expectations of their students, as they want students that will uphold the core values of the occupational therapist field. Therapists have the responsibility of being ethical practitioners, and should always have the health, well-being and best interests of the client as their top priority.
